“…Walau bagaimanapun, semikonduktor seperti ini memiliki jurang tenaga yang lebar (>3.0 eV) dan secara langsung mengurangkan kecekapan aktiviti fotomangkin yang digunakan di bawah tenaga cahaya kerana sebahagian besar tenaga solar yang sampai di permukaan bumi merangkumi julat foton lebih daripada 400 nm (Cheunget et al 1998). Tambahan pula, terdapat masalah penggabungan semula pasangan elektron-lohong (Han et al 2012;Hang et al 2012). Pelbagai cara telah diterokai untuk meningkatkan kecekapan semikonduktor seperti teknik pendopan, modifikasi permukaan dan penghasilan komposit dengan logam tulen atau logam oksida (Ayob et al 2016;Mun et al 2014;Ng et al 2017;Yin et al 2017).…”

“…Diantara berbagai macam semikonduktor, ZnO merupakan salah satu semikonduktor anorganik yang tidak bersifat toksik yang dapat memberikan mobilitas tinggi dan stabilitas termal yang baik. ZnO memiliki jarak pita 3,37 eV dengan energi ikatan 60 meV pada suhu ruang dengan struktur yang stabil yaitu wurtzite [1] . Banyak penelitian yang dilakukan dengan menggunakan ZnO sebagai katalis, baik ZnO sebagai monokatalis, ZnO yang didoping dengan sesama logam (metal-metal) maupun yang didoping dengan senyawa non logam (metal-non metal) karena sifatnya yang serbaguna, kemudahan dalam pembuatan, dan biaya yang relatif murah [2,3,4] .…”

“…Owing to large specific surface area and length to diameter ratio, quasi-one-dimensional (1D) ZnO nanostructures, such as nanowires, nanorods and nanobelts, could potentially be a very good class of catalysis support structures [10][11][12]. However, the high recombination rate of photogenerated electron-hole pairs has limited its commercialization of this technology.…”

SnO2/ZnO nanorod composite photocatalysts have been successfully fabricated via combining the electrochemical deposition (ECD, for ZnO nanorod) with a simple solvothermal growth (for SnO2 nanoparticle). As was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), SnO2 nanoparticles in a tetragonal phase were attached on the side faces of ZnO nanorods to form the nanocomposites. SEM and TEM images indicated that the diameter and the length of the SnO2/ZnO nanorod composites were 100-300 nm and 2-5 µm, respectively. The effect of ECD potential on the microstructure of ZnO nanorobs was also investigated. The observation of the morphologies showed that the optimum spacing of ZnO nanorods grown on Cu substrates were obtained when ECD potential was −0.8 V at 80• C. The photocatalytic behavior of the SnO2/ZnO nanorod composite photocalysts has been examined by monitoring the photodegradation of rhodamine B (RhB) under UV-radiation exposure. SnO2/ZnO nanorod composites showed higher photocatalytic activity toward photodegradation of RhB than bare ZnO nanorods, which was due to the efficient charge separation at the SnO2/ZnO composite photocatalyst interface.
